' It is one ofthe objects of the present invention to provide a tilling machine of the unitary type, that is to say, a construction in which the motor plant itself forms the frame of the machine and all co-acting parts are supplemental thereto.

A further Object of the invention is to provide a tilling machine having a rotary tilling tool, which isso constructed as to follow the inequalities of the ground traveled over and thereby evenly till or work the Soil.

A further object of thel invention is to hich the provide a tillingmachine in w rotary tilling. tool is yieldingly connected to the main portion of the machine to give said tool a tendency to maintain its proper osition relative to thetraction portion of the machine while following the inequalities of the ground traveled over.

A further Object of the invention is to rovide a tilling machine with an adjustable shoe for regulating the depth of work of the revoluble tilling tool.

A further object ofthe invention is to provide a tilling machine having a ll-sliaped axle positioned. to guard thechassis ofthe machine yieldingly mounted thereon 'against shocks due to the rough surface traveled over.

A further-object of the invention is to rovide a tilling machine in which the Vrotary tilling tool thereof is partly supported by a yielding connection to facilitate the lifting of the tool in passing over obstacles. A further object of the invention is to provide a t'lling machine in which the trac# tion mechanism is of a yielding construction and the driving connection therewith is relieved of jolts and shocks by arranging the of which the following- -equivalents thereof.

drivers or other wheels to give in a direction away from the direction of torque -of the driving mechanism.

A further object of the inventionis to provide atilling machine with means for .guiding the tilling tool inv a line parallel with the last furrow worked regardlessy .of the inequalities of the ground or the "in-l exact steering of the machine.

A further object of the invention 'is to provide a tilling machine of simple construction, which is strong and durable and is well vadapted for the purpose described.

With theabove and other objects in view the invention consists of the improved tilling machine and its parts and combinations .as set forth in the claims, and -all In the accompanying .drawing in which the same reference characters indicate the same parts in all of the views:

24 connected thereto which are in mesh with pinions 25 mounted on a transverse shaft 26. The shaft y26 is journaled in the crank case gear connection 27 with the cranked shaft 28 of theengine 8. It will be noted that the is connected by gear wheels 24 are engaged by the pinions 25 in the rear of the cranked axle thus permitting the traction wheels and gearwheels to'give in a direction away from the direction of torque of the pinions and that by this arrangement andlocation of the parts the gear teeth are relieved of the shocks imparted to the traction wheels.

The crank case is provided with a trans- 29 -(only a part bemission gear mechanism ing shown) of ordinary construction for changing the-speed of the parts, and to the shaft 30 ofthis mechanism rear end of the -a universal joint 31, a tiltable shaft 32,. The tiltable shaft is inclosed withina tubular arm or housin 33, the forward end of vwhich .has a ba connection 34 with 'the rear end ortion of the crank case and'surrounding the universal joint and movable .coincident therewith. The ball and' socket connection of the arm .33 permits said arm to revolve as well as to swing to different angles.

he rear end of the tubular varm carries a bearin and gear casing t 35 in which is journale Ua transverse tool'shaft 36 and this shaft is driven by a bevel gear connection 37 or other driving means by the tiltable shaft 32. The tiltable shaft and the tiltable tubular arm extend rearwardly from -a medial portion of the crank'case frame and like.

wisel engage a medial rounded portion of the tool shaft, so that the said.shaft and the tilling tools 38 mounted thereon can follow the inequalities of the ground traveled over. Thetransverse shaft and the tools form .the rotary tilling member of the machine.

The tools 38, whileshown as formedy of plates of metal curved forwardly.. at their outer ends in the direction of travel of the machine, maybe differently constructed, if desired.

: and socket spring members 48'y and 49 on its outer ends, one of In providing the medialv connection'of the dial space 39 not providedwith tilling tools and consequently in tilling the ground a tongue or narrow strip of soil is left .between the tilling tools. To remove this strip and 'to also regulate the depth of cut of the tilling-tools a shoe member 40 is provided which is medially pivotally connected to the gear casing 35. The upper end of the member is provided with .a bolt 41 for adjusting the angle of the. shoe and the lower end portion 42 of the member is in the form of a low or shoe, having a straight base line with a forward point 42 and a'rearward extension 43. vByinclining the base line of the shoe member downwardly or upwardly the depth of the cut of the tilling tools maybe regulated like in plows, and at the same time the shoe member serves to plow and break u the tongue of earth left by -the tilling tools. The rotary 'tilling memberis partly supported-by means of a coiled spring connection 44 attached at oneend to an upstanding arm 45 of the crank case' and at its other end 'to an upstanding v35,.the angular l'relatlon of the sprlngpull to the universal joint helping to equalize the The armA 46 is. also provided with a cable or other connection 47 with the upper portion ofthe engine so that, when desired, the rotary tilling member may be easily raised upwardly .and out o f contact with the ground.

In order to yieldingly hold the tiltable- .90 arm 46 of the casing` tubular arm in a central position with relation to the vehicle proper the said arm is provided with flat spring members 48 attached to opposite sides thereof which diverge outwardly forwardly, and their outer endsare interposed `between the free ends .of rearwardly extending spring members 49 mounted on the' side portions of the crank case chassis, the connection between being in Atransverse alinement with joint 31. j

'The outer ends of the spring members 48 `also bear against the rear corner edges of the crank case frame so that these spring members serve to yieldingly and normally hold the tubular arm .33 in its medial position and at the same time permit the said arm tobe raised and lowered and to swing sidewise in passing obstructions and correcting the. faults of steering.

The tiltable tubular arm 33 is also provided with a transverse extending guide member 50 having disk wheels 51 journaled which is adapted to travel in the furrow just previously cut and` guide they machine in tilling the next parallel furrow. The guide mounted on the tubular swing vertically so that member is Divotally arm and is free to yeither disk wheels may travel in the furrow and while one supp orting wheel is traveling in the furrow, the other is tilted upwardly to travel on the surface of the unworked soil. iThe disk wheels are mounted on the guide arm 'at an angle so that the hubs 52 of upon the surface when the disk wheels are 1n the `furrows below the surface of the soil.

The detail portions of the engine and the various controlling devices have been eliminated from the drawing for simplicity of illustration, but it is to be understood that all necessary parts are contemplated in the complete machine.

From the'foregoing description it will be seen that the, unitary construction provides for the crank case of the engine carrying all of the stresses and strains of the vehicle and the'traction, and that the rotary tilling tool forming part of the machine lis well adapted to compensate for theinequalities of the ground and to perform the functions desired.
